How to change your Cartridge in a Single Lever Kitchen Tap
Follow the 11 easy steps below to replace cartridge in your Single Lever Kitchen Tap:
As a Single Lever Tap can be more complicated due to the position of the Cartridge inside the Tap, we have made a very comprehensive video guide here.
- Make sure to turn OFF the hot and cold water mains as otherwise water will come out of the side of your tap once you access the cartridge.
- Remove the grub screw to loosen the handle. Use the correct size Allen key—typically 2mm or 2.5mm Allen Keys. Take care not to lose the grub screw; placing a cloth or towel underneath the work area can help catch it if it falls. On some single lever taps, a coloured indicator (usually blue/red) on the front conceals the grub screw. Gently remove this indicator using a delicate tool, such as the tip of a knife, taking care not to scratch the tap’s surface.
- Unscrew the silver dome shape. Turn AntiClockwise to loosen.
- Use an appropriate sized spanner (or adjustable spanner) to loosen the Brass Nut. Turn AntiClockwise to loosen
Example of Brass Nut 
5. Remove defective cartridge.
6. Before putting in new cartridge check the inside of the tap body and remove any debris that might be there.
7. Replace and tighten brass nut.
8. Replace silver dome.
9. Refit the lever handle.
10. Refit the grub screw.
11. Turn on the water.

To change a Franke fuji tap cartridge with the narrower stalk coming out of the dome ( https://www.tapsandsinksonline.co.uk/wp-content/uploads/2016/09/fuji-SP1485-Aerator.jpg ) remove the grub screw on the tap handle (not the one on the pillar). The part of the handle that is screwed in at a right angle can stay in place. Then there is a flange covering the dome that is 4cm diameter and 7mm deep. This unscrews from the barrel that inserts into the front of the upright pillar. Once the flange is off the handle comes off but can be a bit sticky; some gentle bangs on the base of the screw in handle in the axis of the stalk may help. Once off the brass screw can be removed to give access to the cartridge
